CONTAINER BOGIE.

Application led December 21, 1926. Serial No. 156,218.

It has heretofore been proposed to provide great Ynumbers of standard containers in which may be placed the freight to be handledy and which may be transferred as a unit, from one carrier to another. rlhis reduces the amount of handling necessary and enables it,

to be done with less expense where cranes, ramps and suitable apparatus have been installed at the terminus to handle such con-V tainers.

The purpose of the present invention .is to, provide an attachment for unit containersy of the above type which will convert them from stationary box like structures toy a unit which can be easily moved about a platform and on and 0E of the carrier. It is necessary that the device be small and easily handled and, above all, readily applied to, or removed from, the desired container.

In such a stationary box-like container having no rollers or wheels permanently attached to its bottom it is desirable that the container be readily transportable from the platform of the consignor to a Ymotor truck, and, upon inal delivery, from a motor truck to the platform of the consignee. It may be more convenient at railroadl terminals to handle the containers by cranes, etc., which are permanently installed. The present invention enables such a container to be used and provides a means for readily transporting the saine.

It will thus be seen that the object of the present invention is to provide an attachment for a' standard unit container which may be readilyV applied to, and removed from the container to render the same easily transportable in the operation'of loading or unloading `from carriers. By relieving the containers of rollers, the weight thereof is distributed over a. large bearing area which is highly desirable in the t-ransportation of the containers.

Reference will now be had to the accompanying drawings for a more detailed description, wherein like reference characters designate like parts, and wherein:

Figure 1 is an elevation, partly broken away and in section, showing the preferred form of the invention. v

Figure 2 is a side elevation, partly broken away and in section, of the embodiment shown in Figure 1.

.Figure 3 is a section taken on line 3-3 of Figure l showing the ratchet mechanism.

Figure 4 is an elevation, partly in section, showing a modified form of the invention.

Figure 5 is a side elevation showing a pair o f the devices of Figure 4 as applied to the side of the container.

In the drawings a represents a container of any desired form now-in use not permanently fitted with wheels, and' provided with a lug d which has a recess d and at its lower portion, co-operating lugs d2 provided with flanges da. A bracket is formed at its lower extremity with a vertical bearing e which carries a caster f having an inverted U-shaped portion f. Between the lugsnf the U-shaped portion is mounted a roller f2 and the caster is securedwithin the bearing by means of nut f3 and washer f4. A recess f5 is formed in the upper portion of the caster, and a pin f, ad]usted by a knurled knob f7 is carried in the bracket member e. Spring f8 normally urges the pin f6 into engaging position with the recess f5. A pin 'fs is carriedwith the pin shaft f6 and is adapted to be received in the slot flo formed in the bracket e. By means of`this structure the caster can be locked against rotation. Advantage of this feature may be taken in two ways. By locking all four wheels it is possible to remove the. container from a motor truck by the ramp track method, since the bogie or truck member, can be made with wheels of the proper gage to engage the ramp track. Furthermore, by locking the two rear wheels, the container can be steered more easily when it is being'pushed or movedin a desired direction.

vAt thelower portion of the bracket eJ are formed oppositely disposed wing-shaped flanges g whichvare formed upon the bracket x tatable nut h is provided havino a bevel gear hl at its upper extremity and liavingan internally threaded portion 7a2. Within this nut is carried a screw i which is operated by the nut, and which has an axial Jgroove i adapted to be engaged by a key i2 mounted upon a pin s which is carried by the bracket e. This structure prevents the screw from turning and results in its upward movement upon rotation of the nut h.

Adjacent the nut L and formed with the bracket e; is provided an extension j formed with a. longitudinal bearing j adapted to receive a shaft jg. adjacent the nut h, is mounted a bevel gear js engaging the bevel gear 7L. The shaft 7'2 is formed with a recess jt to be engaged'by a crank 7c in a Well known manner. At the end of the bearing j', is provided a housing Z I adapted to receive a ratchet wheel Z which is mounted upon the shaft jz. In the lower portion ofthe housing Z is provided a pin Z2 operated by a knurledl nut Zs and pressed against the ratchet wheel 'by spring Z4. It will be seen that the pin may be lifted from the ratchet wheel and turned through 180 to provide a ratchet effect in the opposite direction.

At the top of the screw z' is formed a head i* and a nose '5 which is adapted to be received in the recess d. l

Tn'Figures t and 5, a modified form of the invention is shown. Tn this form, a designates a container provided with blocks or channels a at the bottom and with timber lengths a2 to keep the container od the floor. The channels a may be secured to the containers as by bolts and nuts a3.

On the side of the containers and above each channel piece, are secured suitable brackets 0,4, between which and the container, a lifting arm may be received.

The truck member consists of a housing b, provided at its outer side with a bracket extension Z2', which, with the housing. forms a U-shaped recess t0 receive a roller b2. The roller is mounted on the shaft Z3 extending` between the two U-members.

Slidably mounted within the housing is a lifting rod c provided with a. horizontal hook c which engages the channel or block a when it is raised. Rod c has serrations or ratchet elements 02 on its back and an upwardly extending nose c? which is received in the recess of the bracket, as previously noted. To prevent the bogie or truck member from slippin A down and disengaging the container when t e latter is moved over rough and uneven floors, provision is made for securing the bogie to the container. Thumbscrew m is provided to prevent relative movement between lifting member 0 and housing Z9l when the bogie is in operative position.. (lo-operating holes 0 and p are provided in the nose of the lifting member and the bracket a4 and to the housing is secured, as'by a chain, a pin n which is received in the holes 0 and p and prevents the disengagement of the bo gie from the container. After the bogie has been applied and thelifting member raised to the desired height, the pin n is inserted in the At the end of the shaftl recare@ holes o and p and the thumb screw m tightened. This will prevent the bogie from disengaging the container.

At b4 in housing b there is pivoted a crank Z which receives a handle aZ in the usual manner. A p-awl e is also pivoted at b4 and engages the ratchet teeth 02 to hold the rod c in a lifted position. On the ldwer end of crank d a. pawl f is provided which likewise engages the teeth and through application of suitable force on the lever d', lifts the rod. Ther elements just described constitute the parts of any well known type of jack and form no part of this invention. Fur- 'thermore, the roller previously described may be a swivel caster or other similar form of mechanism without depart-ing from the scope of this invention.

Tn operation, the device is placed against the container so that lifting rod c with its hook c and nose 03 will be in such position, that upon raising the rod, the ends will engage their respective seats and lift the container.

The present invention embodies a. device which may be used on containers of the com- Y mercial form and size to enable them to be readily lrandled. lt is light and stro-ng and can be readily put in use or removed and can be carried by the motor truck to each warehouse. A further advantage of this type of bogie is that very little pressure is brought to bear on the side ofthe container but is applied underneath where it is best able to receive the pressure.

Obviously the devices may be arranged in pairs to form a unitary and staple support for one side of the container.
